On zsh shell, I put into my ~/.zshrc the following function :

ff () {
    parallel -j8 find {} -type f ::: $1/* | grep -i $2
}

The goal is to do a "parellel" version of classical find function.

But unfortunately, it doesn't seem to work : for example, in a directory containing R scripts, I am doing :

ff . '*.R'

But this command doesn't return anything. I would be grateful if someone can see what's wrong with my function ff.

CodePudding user response：

By default grep uses basic regular expressions, so calling the function with another asterisk should work

ff . '**.R'

to ignore files like foo.r.bar

ff . '**.R$'
